Unfortunately, the RadColorPicker
has no built-in support for validation scenarios like yours. I logged your suggestion as a feature request in our PITS
where you can vote for it thus increasing its priority. I also updated your Telerik account accordingly.
In the meantime you'll have to create your own logic to display a validation tooltip. The RadColorPicker ControlTemplate
has no validation elements and you'll have to add such and control their behavior based on your validation logic.
